Character of the water

Jumma lies in the south — a southern acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. Acidification has thinned life down to the hardiest few.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

Moderately deep (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Jumma FVOF. Day permit ~60 kr · annual permit ~300 kr.

  • Pike: keep at most one over 75 cm per day.
  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Jumma

perch predatory fish
typically ~22 cm · can reach 45 cm
Here perch lives on the small stuff — and rewards those who fish small and fine.

typically ~18 cm · can reach 32 cm
Here roach lives on the small stuff — and rewards those who fish small and fine.
trout salmonids
typically ~35 cm · can reach 70 cm
Trout is a sight-hunter here — the clear water means long follows before the take.
whitefish whitefish
typically ~30 cm · can reach 55 cm
Whitefish cruises the open water — the depth it picks follows the light through the day.
sutare fish
typically ~35 cm · can reach 60 cm
Sutare holds the bottom even in clear water — shade and depth are its cover.

Fishing Jumma

The species list of Jumma runs to 7. The predators — perch, pike and trout — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Jumma is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • Acidified water yields few, hardy species.
